Life on Earth: A Natural History by David Attenborough is a television natural history series made by the BBC in association with Warner Bros. and Reiner Moritz Productions. It was transmitted in the UK from 16 January 1979. During the course of the series presenter David Attenborough, following the format established by Kenneth Clark's Civilisation and Jacob Bronowski's The Ascent of Man (both series which he designed and produced as director of BBC2), travels the globe in order to trace the story of the evolution of life on the planet. Like the earlier series, it was divided into 13 programmes (each of around 55 minutes' duration). The executive producer was Christopher Parsons and the music was composed by Edward Williams. Highly acclaimed, it is the first in Attenborough's 'Life' series of programmes and was followed by The Living Planet (1984). It established Attenborough as not only the foremost television naturalist, but also an iconic figure in British cultural life.

The story of Earth is an epic filled with crises, catastrophes, and remarkable, repeated change. Earth traces its origin to simple atoms that were created in the big bang, transformed into heavy elements in stellar explosions, and then forged into a planet inside the nebula that gave birth to the solar system. Like many other planets, Earth went through phases of melting, volcanism, and bombardment by asteroids. But only on Earth did events lead to a flourishing biosphere—life. And once life was established, it drove the evolution of our planet in startling new directions.
